Answer :

In the given scenario, the claim states that the divergent movement of the Jalisco Block away from the North American Plate is the best explanation for the pattern of volcanic activity and earthquakes on the Jalisco Block. To support this claim, you need to identify evidence that aligns with this idea.

One piece of evidence that could support this claim is the presence of mid-ocean ridges on the ocean floor surrounding the Jalisco Block. These ridges are formed due to the divergent movement of tectonic plates, where new crust is created as plates move away from each other. In the context of the claim, the presence of mid-ocean ridges near the Jalisco Block could indicate the divergent movement between the Jalisco Block and the North American Plate.

Another piece of evidence could be the seismic activity in the region. Divergent plate boundaries are known for their seismic activity, including earthquakes resulting from the movement of plates away from each other. If the Jalisco Block shows a pattern of earthquakes that align with this type of plate boundary, it could support the claim of divergent movement between the Jalisco Block and the North American Plate.

By selecting and explaining evidence such as the presence of mid-ocean ridges or seismic activity consistent with divergent plate boundaries, you can effectively support the claim that the divergent movement of the Jalisco Block away from the North American Plate explains the volcanic activity and earthquakes in the region.
